Abstract
Many power ultrasound applications are based on ultrasound cavitation. Because
of the complication of the ultrasound cavitation reaction, it is difficult to make a
direct study on the cavitation course. At present the study on ultrasound
cavitation is mainly through measuring the various effects it brings, where the
TA fluorescence method and the electricity method are relatively effective
methods. This paper adopts a pH-value measurement method to study the
ultrasound cavitation effect in a reverberation field and a traveling wave field.
Comparing the result of the pH-value measurement method with that of the
fluorescence method and the electricity method, we found that they are similar.
In consequence, it proves that the pH-value method is another effective method
to study the sound cavitation effect. Furthermore, another experiment on bi-frequency
irradiation enhancement effect is conducted and the experiment result
measured by the pH-value method which is compared with the measurement
result of the same experiment adopting the electricity method to further prove the
pH-value method’s feasibility. The pH-value method is characteristic of many
merits. Firstly, compared with the TA fluorescent method, it is simpler and
easier. Secondly, because it can adjust the temperature grade according to the
temperature of the sample, the pH-value method reflects the objective laws of the
cavitation effect more effectively than the electricity method when the
temperature of a sample changes in a large range.
Keywords: pH-value, reverberation field, traveling wave field, measuring
method.
